Aha! Now we can enjoy a mouthful of cold drink the instant you open the water bottle. What you need to do is just twist the cap of the bottle. What is the trick?

Well the smart air-tight cap does the magic. When you twist the cap it releases 1.4 g of the powder in to the water. The powder could be your favourite pineapple flavoured tang or green tea. As the drink is made instantly it could be very much refreshing.
Now you don’t need to carry the bulky bottle full of Tang. Just carry the required amount in the cap. I suppose that there is some restriction with the volume of water that the bottle can hold or other wise it will generate drinks of varied dilution.

How is this any different than just carrying around the flavor you want?
Well the difference is just where you carry it. I’ll surely prefer for a twist cap with flavour than carrying it of my own.
